I've been looking for something just like it, with a metronome you could set for whatever exercise/song I'm working on... too bad I can't use it on my second gen ipod... !!! well, I'll just have save my pennies for an ipad..If you ever want to add to your timer app, I have an idea: I would love to be able to set a metronome at a certain bpm for a piece, and enter a goal bpm that I desire to play the piece accurately, then you could increase the metronome by say, 5 or 10 percent every day or week, until you meet your goal! Yay! Just a thought! I will definitely purchase your app when I finally have the bucks for a gadget upgrade,
